A spray drone that can only spray is half an aircraft. The spreading system is what turns a T30 into a dual-role machine — seeds in the morning, granular fertilizer in the afternoon, cover crop before the weather closes in. One airframe, two businesses.

Spreading work rewards precision the same way spraying does: uniform distribution means even stands, even feeding, and even results — while a worn or missing spreader means striped fields and wasted material scattered where it wasn't ordered.

That is why Ares Acres keeps hard-to-find spreading equipment in stock and shipped fast to the U.S.A., helping operators expand their service list, minimize downtime, and keep their aircraft earning when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators, the spreader is a second revenue stream bolted to an aircraft they already own.

🔧 Component Overview

The DJI T30 Agras Drone Spreading System is a complete dry-material distribution system engineered for the DJI Agras T30 agricultural drone.

The system delivers precise, uniform spreading of seeds, granular fertilizers, and plant protection materials — converting the T30 from a spray platform into a dual-role application aircraft. Built from high-quality, durable materials for demanding agricultural duty, it installs with the included manual and hardware kit and integrates for reliable performance over large-area operations.

Commercial spreading operations this system supports include:

• Seed broadcasting and cover crop seeding
• Granular fertilizer application
• Rice seeding operations
• Pasture and forage seeding
• Dry plant protection materials
• Top-dressing programs
• Large-area field coverage
• Precision agriculture missions
• Daily commercial deployments
• Multi-crop contract work

Throughout these operations, spreading systems are routinely exposed to:

• Abrasive granular material flow
• Corrosive fertilizer contact
• Seed and material dust
• Continuous spinner and feed vibration
• Heavy hopper loading cycles
• Field moisture and humidity
• Rinse and clean-out cycles
• UV exposure
• Transport handling between sites
• Long commercial operating hours

Over time, this duty wears feed mechanisms, abrades distribution components, and degrades housings — and worn spreading equipment means uneven distribution the crop will show all season.

The Spreading System helps maintain:

• Precise, uniform material distribution
• Even field coverage over large areas
• Dual-role aircraft capability
• Efficient seed and fertilizer application
• Reliable material feed and flow
• Consistent operational standards
• Increased fleet capability
• Maximum aircraft utilization
• Reliable commercial operation

For operators whose aircraft should earn in every season, spreading capability doubles the calendar.

Before you spend money, decide whether the complaint is a rate problem or a pattern problem, because they live in different halves of the system. A rate problem means the right shape of spread but too much or too little product going out, and it points at the metering gate and its drive. A pattern problem means the correct total weight leaving the aircraft but landing unevenly across the swath, and it points at the throwing unit, its disc, and its vanes. Chasing one with the tools for the other is how a week disappears.

Measure the rate on the ground instead of trusting the display. Weigh a known amount of the exact product you are about to fly into the hopper, secure the aircraft with the propellers off or restrained, run the metering system over a tarp for a timed period at a set rate, then weigh what came out and what stayed behind. Do it twice. Two runs that agree with each other and with the commanded rate clear the metering side completely.

Test the pattern with pans rather than with your eyes on a field. Set a row of shallow, straight-sided containers across the full working swath on level ground, run a pass, and compare what each one catches. What you are looking for is not just left-to-right balance but the shape of the taper at the edges, because a spreader lays down a pattern that thins toward the outside and depends on overlap from the next pass to even out. A pattern with a sharp shoulder or a hole in the middle will stripe no matter how you fly it.

Rule out the flight plan before you condemn the hardware. Striping in a finished field is produced just as often by line spacing that does not match the material being thrown as by worn equipment. Heavy, dense fertilizer carries further than light coated seed out of the same machine at the same settings, so a swath width that was right in the fall can be wrong in the spring. Run the pan test with the actual product, work out where the pattern really ends, and set your spacing from that.

Listen to the system through a full cycle with the hopper empty and the aircraft safe. The throwing unit should spin up smoothly and hold a steady note. A drive that hesitates, surges, or changes pitch under no load has a mechanical or electrical problem that a full hopper will only make worse. The metering gate should open and close cleanly and completely, with no hesitation and no grinding, and you should be able to see daylight change at the opening as it moves.

Check the changeover before you check the machinery. A spreading system that will not initialize, reports the wrong payload, or refuses to meter is often a fitment and connection problem rather than a broken part: a connector not fully latched, a payload the aircraft has not been told about, or spray-side hardware still fitted that should have come off. Confirm the aircraft recognizes the spreading payload and shows sensible readings before you take anything apart.

⚙️ Functional Purpose

The Spreading System is designed to distribute dry materials precisely and uniformly from the DJI Agras T30.

The component helps:

• Broadcast seeds evenly across fields
• Apply granular fertilizer at consistent rates
• Distribute dry plant protection materials
• Convert the T30 to dual-role operation
• Cover large areas efficiently
• Maintain uniform distribution patterns
• Install with included manual and hardware
• Replace worn or damaged spreading equipment
• Integrate reliably with the T30 platform
• Support simple setup and low maintenance
• Expand seasonal service offerings
• Increase fleet capability
• Keep spreading equipment field-ready

Even crops start with even distribution — and even distribution starts with healthy spreading equipment.

A solid spreading system keeps material landing where it's ordered, acre after acre, season after season.

Worn or damaged spreading equipment may contribute to:

• Striped, uneven field coverage
• Inconsistent application rates
• Wasted seed and fertilizer
• Feed jams and flow interruptions
• Patchy stands and uneven feeding
• Interrupted spreading missions
• Unexpected downtime
• Customer coverage complaints
• Reduced fleet capability

Replacing worn equipment restores the distribution uniformity the results depend on.

Finish with the spray side properly before the spreader goes on. Drain the tank and run the plumbing out, because a line that drips residual chemistry onto or into a hopper of seed creates a problem no rate setting will fix. Wash and dry the aircraft, particularly the payload area and anything above the hopper opening, then cap or secure the spray fittings so nothing hangs loose. The changeover is the one moment where the two roles can contaminate each other, and it costs ten minutes to prevent.

Do the changeover with the aircraft powered down and the batteries out, on level ground, with the airframe supported. Dry-fit the system before committing to fasteners: offer it up, confirm the mounts line up without forcing anything, and check that nothing fouls the arms, the legs, or the sensing hardware on the underside of the aircraft. If a mount has to be pulled into place with a bolt, something is not sitting where it belongs and the fastener is being asked to do a job it will lose.

Keep the hardware kit and the manual with the system, and use them. The mounting hardware supplied with a spreading system is specific to the changeover, and a mixed handful of shed bolts is how a hopper ends up hanging on the wrong thread engagement. Start every fastener by hand, draw them up in a cross pattern in stages rather than one at a time, and never finish the job with an impact driver. Bag whatever spray-side hardware you removed and label it, because you will want it back at the end of the season.

Route and land the electrical connections deliberately. Support the harness so nothing takes weight or rubs on an edge, seat every connector until it locks, and confirm no lead is trapped under a mount foot or squeezed against a bracket. Then check the routing again with the system fully mounted, because a lead that had clearance during a dry fit can end up pinched once the last fastener comes down. Intermittent metering in flight is very often a connection rather than a mechanism.

Get the load sitting square. A hopper that is mounted off center or not level makes the aircraft fly out of trim, and it works one side of the airframe harder for every hour of the campaign. Confirm the system sits flat on all its mounting points with no preload, that it does not rock when you take hold of it, and that it is centered the way the mounting hardware intends. Then load evenly rather than dumping product into one side and letting it find its own level.

Commission the system before you commit a field to it. Power up with the hopper empty and confirm the aircraft recognizes the payload, then zero or tare any weighing function, then run a static flow test with real product over a tarp, then run the pan test and set your swath spacing from what you measured. Only then fly a field. Every one of those steps has caught a fault for somebody, and skipping straight to the third pass of a paying job is how you find out about them the expensive way.

⚠️ Common Replacement Indicators

Replacement or addition may be recommended when operators observe:

• T30 aircraft not yet spreading-equipped
• Uneven or striped distribution patterns
• Worn or abraded feed mechanisms
• Damaged distribution components
• Fertilizer corrosion on system parts
• Cracked or fatigued housings
• Feed jams and inconsistent flow
• Material leakage from worn seals
• Expanding into seeding contracts
• Maintenance inspection findings
• Fleet capability standardization
• Seasonal equipment preparation
• Long-term commercial wear

Common causes of spreading system wear include granular abrasion scouring feed paths, fertilizer corrosion attacking metal and plastic alike, vibration fatiguing mounts and housings, and moisture cycling through clean-outs — dry material is harder on equipment than liquid, and experienced crews flush and inspect the system after every material change, replacing worn components before they turn into striped fields.

For commercial operators, sound spreading equipment is almost always cheaper than re-seeding the stripes a worn system leaves behind.

A finished field that is striped in a regular, repeating pattern matching the flight lines. That is a swath and overlap problem: the pattern's edges are not reaching each other, either because the equipment throws narrower than it used to or because the spacing was set for a different material. Regular stripes are geometry. Irregular blotches and patches are usually flow.

A pattern that is consistently heavier on one side of the aircraft than the other. That is the throwing unit, not the hopper. Look for a vane that has worn shorter or more rounded than its partners, a disc that is no longer running true, debris packed on one side of the assembly, or hardened residue built up on one vane and not the others. A worn vane releases material later than a sharp one, and the pattern shifts with it.

Output that falls off through a load even though the setting has not changed. Residue built up on the interior walls and around the metering opening changes how product feeds, and the effect grows as the level drops and the head of material above the outlet gets smaller. The rate is right at the start of a full hopper and wrong by the end, which is exactly the pattern that makes operators think the aircraft is misreporting.

Flow that jams and clears, jams and clears. Damp or caked product bridging over the outlet is the first suspect, followed by a foreign object such as a lump, a clod, or a piece of bag in the load. If it happens with dry, screened product on a clean system, look at the feed path for wear and at the metering drive for a slipping or laboring motor.

Product leaking, dribbling, or dusting out of the system where it should not. Check the seals and gaskets around the hopper joints, the metering opening, and any access panel. Fine fertilizer dust escaping into the airframe is not a cosmetic problem, because it is hygroscopic and corrosive and it goes to work on fasteners, connectors, and any exposed metal it settles on.

Corrosion blooming on hardware, and housings that have gone chalky, faded, and dull-sounding when tapped. Dry material is harder on equipment than liquid, and the combination of abrasion, fertilizer chemistry, and sun through a season takes both surface finish and impact strength out of the structure. A housing that has lost impact strength cracks at a mounting point on a firm landing it would have shrugged off when new.

📐 Specifications

Component Type: Drone spreading system / dry material distribution system

Compatibility:

• DJI Agras T30

Package Quantity: 1 Complete System + Installation Manual and Hardware Kit

Installation Area: DJI Agras T30 payload system

Function: Distributes seeds, granular fertilizer, and dry plant protection materials

Design: Precision distribution system for uniform large-area coverage

Construction: High-quality, durable materials for agricultural duty

Mounting Type: Direct-fit system with included hardware

Application: Agricultural drone spreading and seeding operations

Hopper Capacity, Rated Dry Payload, and Spread Width: Not published in this listing. Spread width in particular is not a fixed property of the machine, because it changes with the density, size, and shape of the product being thrown. Take payload and capacity figures from the DJI documentation for your aircraft, and establish working swath width yourself with a pan test using the material you are actually flying.

System Dimensions and Empty Weight: Not published here. Compare the system against the equipment or payload it is replacing before fitting, checking mounting point positions, overall footprint, and clearance to the arms, the legs, and anything mounted on the underside of the aircraft. Fit is a question of clearance in flight, not only of whether the bolts line up on a bench.

Mounting Hardware Torque: Not published in this listing. Use the DJI figure for your airframe with a calibrated wrench and follow the installation manual supplied with the system. A payload mount that is drawn up by feel is either loose enough to fret and elongate its holes or tight enough to crush or strip what it threads into, and both show up as a hopper that has moved by the end of a campaign.

Material Compatibility: Not published in this listing beyond seed, granular fertilizer, and dry plant protection materials. Coarse, sharp, sticky, or unusually corrosive products wear feed paths and attack housings at very different rates than clean screened seed does. Confirm suitability with the DJI documentation and with your material supplier before an unfamiliar product goes into the hopper.

🚜 Necessary For

This system is ideal for:

• DJI Agras T30 operators
• Farmers operating application drones
• Commercial spreading contractors
• Seeding service providers
• Agricultural aviation companies
• Fleet maintenance managers
• Agricultural drone technicians
• DJI Agras service providers

When the calendar has seasons the sprayer can't serve, spreading capability fills them.

Be precise about which piece you are buying. This listing is the complete dry-material system with its installation manual and hardware kit. The hopper or tank on its own, the throwing and distribution unit on its own, and the spray tank are all separate items with their own part numbers. If your fault is a cracked hopper, or a worn disc, you may not need the whole system, and if you are converting an aircraft that has never spread, a single sub-assembly will not get you there.

Spreading systems from different Agras generations look nearly identical in photographs and differ in exactly the ways that matter: mounting interface, connector, and how the aircraft recognizes the payload. Order by aircraft model and by the number on the equipment you removed, not by a resemblance in a listing image. A system that is close but not right may mount and still fail to initialize, which is a worse outcome than one that obviously does not fit.

Do not confuse this with the spray payload it replaces. The spray system holds liquid and plumbs to pumps, hoses, and nozzles, and its failures are pressure, flow, and leaks. The spreading system holds dry product and meters it into a powered throwing unit, and its failures are rate drift, bridging, and pattern shape. Operators running both roles keep the two sets of hardware, fasteners, and cleaning routines separate, because mixing them wastes time in both directions.

💡 Why This Part Matters

The economics of a commercial drone operation come down to utilization: how many days a year does the aircraft earn? A spray-only T30 earns during spray seasons and sits the rest — while the spreading system opens seeding windows, cover crop contracts, and granular fertilizer programs to the same aircraft, the same operator, the same truck.

The quality of that second revenue stream depends entirely on distribution uniformity. Customers judge spreading work by the field it grows — stripes and patches advertise worn equipment all season long, while uniform stands quietly book next year's contracts.

The Spreading System helps maintain:

• Dual-role aircraft economics
• Uniform, professional distribution
• Expanded seasonal service offerings
• Efficient large-area coverage
• Reliable material feed and flow
• Professional fleet standards
• Increased aircraft utilization
• Reliable commercial performance
• Long-term operational confidence

Running without solid spreading capability, operators risk:

• Aircraft idle between spray seasons
• Seeding contracts passed to competitors
• Striped fields from worn equipment
• Wasted material on uneven passes
• Customer coverage complaints
• Unexpected downtime
• Lost application opportunities
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the spread. Protect the stand. Protect the mission. Protect the season.

Professional DJI Agras operators understand that aircraft earn their keep through utilization. Equipping the T30 with a solid spreading system means revenue in every season instead of a sprayer waiting for spray weather — and that difference is what separates a good season from a frustrating one.

While the system is off the aircraft, inspect the mounting interface on the airframe rather than only the equipment. Look for elongated or ovalled mounting holes, cracks radiating from a boss, worn or polished latch faces, and packed fertilizer dust in every seam and pocket. A hopper that has been working loose has been hammering the airframe as much as itself, and fitting new equipment onto a worn interface starts the loosening over again immediately.

Go over the throwing unit closely even if the pattern still looks acceptable, because it wears gradually and you calibrate around the wear without noticing. Compare the vanes against each other for length and edge profile, check the disc for erosion and for a wobble as you turn it, feel the drive for roughness and rock it for play, and clear any hardened residue. Wear here does not announce itself; it narrows the pattern a little at a time until the overlap you set in the spring is no longer enough.

Chase the dust to where it has been going. Fine fertilizer that escapes a seal does not stay put, and it collects on fasteners, in seams, around connectors, and on any exposed metal below the hopper. It draws moisture out of the air, and what it leaves behind is corrosion in places nobody inspects. Wash and dry those areas thoroughly while the payload is off, look for green or white bloom around hardware, and fix the seal that let the dust out in the first place.

What shortens a spreading system is mostly avoidable and mostly happens on the ground. Product left in the hopper overnight cakes and has to be chipped out, which scores the surfaces it feeds over. Pressure washing straight at the metering drive, the bearings, or the connectors pushes water and grit exactly where they do the most harm. Sunlight through a season chalks and embrittles housings. Heavy items stacked on stored equipment crack mounts that flight loads never would have.

Treat the end of a spreading campaign as the service, not the start of the next one. Empty the system, wash it out, dry it completely, inspect the vanes and the feed path, and store it out of the sun with the lid loose so it can breathe and nothing stacked on top. Keep the hardware kit and the manual with the equipment. The parts of a changeover that go missing over a winter are small, and the day you find out is the morning a short seeding window opened.

My field came up striped. Is that the spreader or the way I flew it?

Separate the two before you spend anything. Regular stripes that repeat with your flight lines are almost always a swath and overlap problem, because a spreader lays down a pattern that thins toward its edges and relies on the next pass to fill it in. Irregular blotches point at flow. Run a pan test across the full swath with the actual product, look at the shape of the pattern rather than only its total, and set your line spacing from what you measured.

Do I have to recalibrate when I change from fertilizer to seed?

Yes, and treat it as a new setup rather than an adjustment. Density, particle size, shape, and any coating all change both how fast product meters out and how far the throwing unit carries it, so the same settings that were right for a dense granular fertilizer will put a light coated seed down at a different rate over a narrower swath. Weigh a timed static run for rate, run a pan test for width, and set spacing from both.

The rate is right at the start of a load and light by the end. What is that?

That is usually residue on the interior surfaces and around the metering opening changing the way product feeds, and the effect gets stronger as the head of material above the outlet drops. Empty the hopper, clean the feed path and the opening thoroughly, dry it, and repeat a timed static test at full and at part load. If it still falls off with clean surfaces, look at the metering drive laboring under load and at the outlet for wear.

The pattern is heavier on one side. Which part do I look at?

The throwing unit, not the hopper. Compare the vanes to one another for length, edge profile, and residue build-up, check the disc for erosion and for running true, and feel the drive for roughness or play. A vane that has worn shorter or rounder releases material later than its neighbors, which shifts weight to one side of the pattern. A hopper problem shows up as the wrong total going out, not as a lopsided distribution of the right total.

Can I leave the spreading system on the aircraft and switch back and forth as jobs come in?

Operators do, but the changeover is where the two roles contaminate each other, so give it the time it needs. Drain and run out the spray plumbing, wash and dry the aircraft and especially anything above the hopper opening, and secure loose spray fittings before the spreader goes on. Coming the other way, get the fertilizer dust off the airframe before it sits. Keep both hardware kits labeled and together, because that is what actually slows a changeover down.

What is the safe way to clean the system between materials?

Empty it completely, then get the residue out mechanically and with water rather than by attacking it. Avoid putting a pressure washer straight at the metering drive, the bearings, the sensors, or any connector, because water and grit driven into those places cause more damage than the residue would have. Dry the system fully before it is stored or refilled, since leftover moisture is what turns the next load of hygroscopic product into a solid block.
